The Malay community in Malaysia have eaten traditional vegetables and herbs (ulam) for generations. Some of the commonly eaten ulam include jering (Archidendron pauciflorum (Benth.) I.C. Nielsen), papaya (Carica papaya L.), pegaga or Asiatic pennywort (Centella asiatica (L.) Urb.), ulam raja (Cosmos caudatus Kunth), turmeric (Curcuma longa L.), sambung nyawa or longevity spinach (Gynura procumbens (Lour.) Merr.), peria katak or bitter melon (Momordica charantia L.), kari or curry leaves (Murraya koenigii (L.) Spreng.), selom or water celery (Oenanthe javanica (Blume) DC) and petai or stink bean (Parkia speciosa Hassk.). They are eaten fresh as salads, blanched or cooked.

There has been renewed interest in plant-based diet and medicinal formulations for the prevention and treatment of many chronic diseases including diabetes mellitus (Guasch-Ferré et al. 2017; Chukwuma et al. 2019; He et al. 2019). Parkia speciosa Hassk (bitter or stink bean) is an edible legume belonging to the family Fabaceae. It is commonly found in Southeast Asian countries particularly Thailand, Malaysia, Indonesia, and Philippines (Ghasemzadeh et al. 2018). In Thailand, it is known as “sator” and the beans obtained from the pod is widely consumed and utilised for culinary purposes in southern Thailand (Suvachittanont et al. 1996; Chankhamjon et al. 2010). Traditionally, P. speciosa is used for treating stomach pain, liver diseases, diabetes, worm infestation, hypertension, heart problems, and headache (Ghasemzadeh et al. 2018; Gui et al. 2019). A large number of chemical constituents, including polyphenols, terpenoids, fatty acids, alkaloids, saponins, and cyclic polysulphides have been either identified or isolated from the seeds of the plant (Kamisah et al. 2013; Gui et al. 2019). In addition, numerous studies have also reported its health benefits and pharmacological properties including antioxidant, anti-inflammatory, anticancer, antibacterial, and antiangiogenic properties (Aisha et al. 2012; Sakunpak and Panichayupakaranant 2012; Kamisah et al. 2013). The empty pods of the plant are usually discarded after removing the seeds for consumption, however, these empty pods have been reported to have higher concentration of polyphenolic compounds compared to the seeds, suggesting their potentials as an excellent antioxidant agent (Kamisah et al. 2013; Gui et al. 2019). Since ROS and oxidative stress has been suggested as the major culprit in the onset and progression of diabetes mellitus, it is therefore a reasonable rationale to explore the potentials of P. speciosa empty pods against diabetes. Based on the afore mentioned information, this present study investigated the effects of polyphenolic-rich extract from Parkia speciosa empty pods on diabetes mellitus induced by streptozotocin in combination with high-fat diet.
